Description

Technical Field

[0001] This invention relates to the field of soil and water conservation technology, and specifically to a method for preparing concrete to prevent soil and water loss. Background Technology

[0002] Protecting against soil erosion is carried out based on the principle of adjusting land use structure and combining management with development. Climate factors, topography and geology, vegetation, rapid population growth, and human factors are all major causes of soil erosion. The most widespread types of soil erosion can be divided into three categories: water erosion, gravity erosion, and wind erosion.

[0003] Currently, there are three common methods for protecting slopes in areas such as farmland, roads, water conservancy, and rivers and lakes: The first is to use components such as hexagonal blocks, hinged slope protection bricks, and concrete frames to protect slopes. This method has a short effective protection time, and after a period of use, it not only causes soil erosion but also leaves safety hazards due to slope loosening. The second method is to use concrete full coverage or rough stone masonry for protection. This protective structure is relatively resistant to erosion and has a longer effective protection time, but its heat island effect is more obvious, it cannot be planted, and the ecological effect is very poor. The third method is to protect by planting vegetation. This method cannot resist the impact of harsh climate and livestock damage, and its protective effect is small. Summary of the Invention

[0004] Therefore, the present invention provides a concrete preparation method for preventing soil erosion, in order to solve the above-mentioned problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] According to a first aspect of the present invention, a method for preparing concrete to prevent soil erosion is provided, the specific steps of which are as follows:

[0007] Step 1: Mixing and Preparing Materials: Mix the raw materials for ecological concrete for soil and water conservation in a certain proportion to prepare ecological concrete slurry.

[0008] Step 2, Casting and Molding: Using transportation equipment, the ecological concrete slurry is transported to the designated construction site or molding site for casting and molding to obtain ecological concrete slope protection components;

[0009] Step 3: Covering with soil and planting: Lay the ecological concrete slope protection components along the slope surface, and then lay planting soil and plant vegetation on the ecological concrete slope protection components;

[0010] The components of the ecological concrete slurry include coarse aggregate, cementitious materials, water, dewatering agent, and alkali-resistant agent.

[0011] Furthermore, the composition of the ecological concrete slurry, by weight, includes 100 parts coarse aggregate, 100 parts cementitious material, 30 parts water, 1 part dewatering agent, and 1 part alkali-resistant agent.

[0012] Furthermore, the specific steps for preparing the ecological concrete slurry include:

[0013] S1. Material selection: Select coarse aggregate with the required particle size, wash it with water and let it air dry naturally.

[0014] S2. Mixing: According to the proportions of coarse aggregate, cementitious materials, water, dewatering agent, and alkali-resistant agent in the composition of ecological concrete slurry, each component is added to a high-power forced mixing device. The components are then thoroughly mixed for a fixed time using the high-power forced mixing device to obtain ecological concrete slurry.

[0015] Furthermore, the mixing of the ecological concrete slurry includes primary mixing and secondary mixing. The primary mixing involves mixing coarse aggregate and cementitious material in a 1:1 ratio in a high-power forced mixing device. The secondary mixing involves adding water, water-reducing agent, and alkali-resistant agent in proportion to the high-power forced mixing device used in the primary mixing and mixing them.

[0016] Furthermore, the coarse aggregate is selected from single-size large-particle aggregates with a diameter of 25-30mm.

[0017] Furthermore, the ecological concrete slope protection components are cast and molded on the slope surface in different sizes and shapes, and the coarse aggregates in the ecological concrete slurry of the ecological concrete slope protection components form permeable pores.

[0018] Furthermore, the slope surface is provided with several structural frames that correspond one-to-one with the ecological concrete slope protection components, and the ecological concrete slope protection components are located inside the structural frames.

[0019] Furthermore, the ecological concrete slurry is continuously and uniformly agitated in the transport container during the transportation process by the transport equipment.

[0020] The present invention has the following advantages:

[0021] 1. This method for preparing concrete to prevent soil erosion involves installing ecological concrete slope protection components along the slope surface. These components are formed by casting ecological concrete slurry, which is a mixture of coarse aggregate, cementitious materials, water, dewatering agent, and alkali-resistant agent. It abandons the traditional characteristics of concrete, such as impermeability and density, and instead emphasizes its heavy weight, large pore size, high permeability, high air permeability, and ability to be planted with vegetation. Ecological concrete slope protection components of different sizes, specifications, and shapes can be installed in sections along the slope surface, either cast-in-place or precast. The surface has unevenly distributed large-diameter pores. By covering the surface with soil and planting vegetation, the roots penetrate the pores of the slope protection layer, providing dual protection to the slope soil using the weight of the concrete and the root system. This simultaneously increases structural stability, improves shear strength and erosion resistance, ensures permeability and air permeability, and enhances aesthetics.

[0022] Using this technology can improve the structural stability of fragile slopes, increase shear strength, enhance erosion resistance, improve air and water permeability, increase ecological benefits, improve landscape appearance, improve soil and water conservation, and improve construction methods, procedures, and time. It also allows for easy quality control, requires less equipment, and results in low construction and maintenance costs.

[0023] 2. This method for preparing concrete to prevent soil erosion controls the porosity of the ecological concrete slope protection components by using a combination of large-diameter, single-grade coarse aggregate and cementitious materials, ensuring the permeability and air permeability of the finished product; by adding a certain amount of rainwater-reducing agent to ensure the bonding strength of coarse aggregate and cementitious materials, improving structural stability and shear strength; and by adding a certain amount of alkali-resistant agent to reduce its alkali content, protecting the vegetation's growth environment and improving the survival rate and ornamental value of the vegetation.

In addition, the ecological concrete slurry composition, by weight, includes 100 parts coarse aggregate, 100 parts cementitious material, 30 parts water, 1 part dewatering agent and 1 part alkali-resistant agent.

[0036] The technical effects achieved by the above embodiments are as follows: through technical adjustment, the original 50 parts of fine aggregate are completely removed and replaced with 100 parts of coarse aggregate; the continuous particle size coarse aggregate is replaced with a single particle size coarse aggregate; through the above two adjustment methods, the porosity, water permeability and air permeability created by the present invention can be effectively improved, and one part of alkali-resistant agent is added to reduce the impact of the total amount of harmful alkali in the cementitious material on the vegetation growth environment.

[0037] Example 3

[0038] like Figure 1 and Figure 2 As shown, a method for preparing concrete to prevent soil erosion includes all the contents of Example 2. Furthermore, the specific steps for preparing the ecological concrete slurry include:

[0039] S1. Material selection: Select coarse aggregate with the required particle size, wash it with water and let it air dry naturally.

[0040] S2. Mixing: According to the proportions of coarse aggregate, cementitious materials, water, dewatering agent, and alkali-resistant agent in the composition of ecological concrete slurry, each component is added to a high-power forced mixing device. The components are then thoroughly mixed for a fixed time using the high-power forced mixing device to obtain ecological concrete slurry.

[0041] Furthermore, the mixing of the ecological concrete slurry includes primary mixing and secondary mixing. The primary mixing involves mixing coarse aggregate and cementitious material in a 1:1 ratio in a high-power forced mixing device. The secondary mixing involves adding water, water-reducing agent, and alkali-resistant agent into the high-power forced mixing device of the primary mixing device in a certain proportion.

[0045] The technical effect achieved by the above embodiments is that the porosity is controlled by using a combination of large-particle-size, single-grade coarse aggregate and cementing materials to ensure the water permeability and air permeability of the finished product.

[0046] Example 5

In addition, the ecological concrete slope protection components are cast and molded on the slope surface in different sizes and shapes, and the coarse aggregates in the ecological concrete slurry of the ecological concrete slope protection components form permeable pores.

[0048] The technical effect achieved by the above embodiments is that the ecological concrete slope protection components on the slope surface have good permeability.

[0049] Example 6

[0050] like Figure 1 and Figure 2 As shown, a concrete preparation method for preventing soil erosion includes all the contents of Example 5. In addition, the slope surface is provided with a number of structural frames corresponding one-to-one with the ecological concrete slope protection components, and the ecological concrete slope protection components are located inside the structural frames.

[0051] Furthermore, the ecological concrete slurry is continuously and uniformly agitated in the transport container during the transportation process by the transport equipment.

[0052] The technical effect achieved by the above embodiments is that the ecological concrete slope protection component is located inside the structural frame, and the structural frame fixes the ecological concrete slope protection component to the slope surface, preventing the ecological concrete slurry from solidifying during transportation.

[0053] The method of using this invention is as follows: Select single-sized large-particle aggregate with a diameter of 25-30mm, wash it clean with water, and allow it to air dry naturally. Mix the coarse aggregate and cementitious material in a 1:1 ratio in a high-power forced mixing equipment. Then, add water, dewatering agent, and anti-alkali agent to the high-power forced mixing equipment in the same proportion and continue mixing until uniformly mixed to obtain ecological concrete slurry for soil and water conservation. Use transportation equipment to transport the ecological concrete slurry to the designated construction site or molding site for pouring and molding to obtain ecological concrete slope protection components. The ecological concrete slope protection components are laid along the slope surface or poured within the structural frame. Planting soil and vegetation are laid on the ecological concrete slope protection components. The vegetation roots penetrate through the gaps in the slope protection layer, using the self-weight of the concrete and the vegetation roots to provide double protection for the slope soil, while simultaneously increasing the structural integrity. This invention improves stability, shear strength, and erosion resistance; ensures permeability and air permeability; and enhances aesthetics. Through technical adjustments, it completely removes the original 50 parts fine aggregate and replaces it with 100 parts coarse aggregate; it also changes the continuous-sized coarse aggregate to a single-sized coarse aggregate. These two adjustments effectively improve the porosity, permeability, and air permeability of the resulting structure. Adding one part of alkali-resistant agent mitigates the impact of the total alkali content in the cementitious material on the vegetation growth environment. This technology improves the structural stability of fragile slopes, resulting in high shear strength, strong erosion resistance, excellent permeability and air permeability, high ecological benefits, good landscape appearance, and good soil and water conservation. The construction method is simple, the construction process is straightforward, the construction period is short, the construction quality is easy to control, the equipment used in the process is minimal, and the construction and maintenance costs are low.
